#129 Newsletter list broken (shows too much entries)

The newsletter list shows too many entries due to a
broken sql statement (the statement returns as many
rows as there are entries in the tables it joins over).
This does not occur for the administrator or guests.

Possible patch as usual included :)
NOTE: this patch is against the cvs version not against
the modified versions you get due to applying former
patches I submitted.
